氯化物助熔剂对Y3Al5O12∶Ce3+荧光粉性能的影响

摘要选用卤化物LiCl、NaCl、KCl和SrCl2等作为助熔剂，合成了一系列YAG∶Ce粉体，并研究了助熔剂对YAG∶Ce荧光粉晶相、形貌和发光性能的影响。结果表明适量助熔剂有利于YAG∶Ce荧光粉的晶化，合成的荧光粉具有石榴石的结构，规则的形貌和窄的粒度分布。添加适量助熔剂可以提高YAG∶Ce荧光粉的发光强度。最适宜的添加量分别是：LiCl 10%，NaCl 7%,KCl 7%，SrCl2 4%。

Abstract： In this paper,LiCl,NaCl,KCl or SrCl2 were selected as fluxes and the effect of the chlorides fluxes on crystallite,morphology and luminescence properties of the YAG∶Ce phosphor powders were investigated.It was found that the YAG∶Ce phosphors obtained from initiative materials containing chlorides fluxes exhibited typical garnet structure and no impurity phase.The YAG∶Ce particles are regular spherical or elliptical morphology,with small size and narrow granular distribution.The emission intensities of the YAG∶Ce phosphors increased with adding appropriate amounts of chlorides fluxes to initiative materials.The optimum amounts of chloride fluxes were 10% for LiCl,7% for NaCl,7% for KCl or 4% for SrCl2,respectively.
